Todd Lipcon reopened HADOOP-7227: --------------------------------- > Remove protocol version check at proxy creation in Hadoop RPC. > -------------------------------------------------------------- > > Key: HADOOP-7227 > URL: https://issues.apache.org/jira/browse/HADOOP-7227 > Project: Hadoop Common > Issue Type: Improvement > Components: ipc > Reporter: Jitendra Nath Pandey > Assignee: Jitendra Nath Pandey > Fix For: 0.23.0 > > Attachments: HADOOP-7227.2.patch, HADOOP-7227.3.patch, > HADOOP-7227.4.patch > > > Currently when a proxy is created for a protocol, there is a round trip of > messages to check the protocol version. The protocol version is not checked > in any subsequent rpc which could be a problem if the server restarts with a > new protocol version. This issue and also the additional round-trip at proxy > creation can be avoided if we add the protocol version in every rpc, and > server checks the protocol version for every call. -- This message is automatically generated by JIRA.
